Wrestlemania is the perfect opportunity

I know this has been done to hell and back and it is very unlikely to happen.

But Mania is the perfect opportunity to turn Cena heel.

WWE are expecting him to get booed out of the building when he wins, so why would they have that in the background of a career milestone, imagine a Cena career highlight DVD years down the line, they will for certain have Him VS rocky in there.

So why not make the crowd reaction fit.

It could be simply done, have him hire the Shield, to help him take out Rocky, then complain about Rocky been given the title despite only working less than ten shows, while Cena has worked his ass of for years, every day of the week.

The you could have him on a dominant run, while building up faces to challenge him, imagine Super Cena also with the mindset of 'I'll do whatever it takes to win... even if it means bending the rules', have him keep the title until next Mania, and then have the next big thing take it from him.

I know my wording is awful, and this is highly unlikely to happen, but I just felt like throwing it out there.

I agree but disagree. Realistically, a cena heel turn will never happen, but, lets say it did. Personally, i think him turning heel at wm would be epic, and if he stuck being a heel for a full year would be good. I wouldnt have him hold the title for a whole year though. Instead, id have him hold it for 6 months, and then give the title to a face who is a main eventer or on the verge of main eventing. Heck you could do it to wade barrett or ziggler or rhodes. Then from there cena just starts going wild on the roster for a few months, until taker returns, and cena says he wants to accomplish the one thing no one has done, beat taker at wm. Boom, we get taker vs cena at wm 30, and it would be perfect for taker to retire at that point. But again...we will never see a cena heel turn
